Storks everywhere, rejoice. A new study shows that the ability to stand on one leg for at least 10 seconds is strongly linked to the risk of death over the next 7 years.

According to the findings, people in middle age and older who couldn’t perform the 10-second standing test were nearly four times as likely to die of any cause – heart attacks, strokes, cancer, and more – in the coming years than those who could, well, stand the test of time.

Claudio Gil Araújo, MD, PhD, research director of the Exercise Medicine Clinic-CLINIMEX in Rio de Janeiro, who led the study, called the results “awesome!”

“As a physician who has worked with cardiac patients for over 4 decades, I was very impressed in finding out that, for those between 51 and 75 years of age, it is riskier for survival to not complete the 10-second one-leg standing test than to have been diagnosed as having coronary artery disease or in being hypertensive” or having abnormal cholesterol, Dr. Araújo said in an interview.

The findings appeared in the British Journal of Sports Medicine.

Researchers have known for at least a half century that balance and mortality are connected. One reason is falls: Worldwide, nearly 700,000 people each year die as a result of a fall, according to the World Health Organization, and more than 37 million falls annually require medical attention. But as the new study indicates, falls aren’t the only problem.

Dr. Araújo and colleagues have been working on ways to improve balance and strength as people age. In addition to the one-legged standing test, they have previously shown that the ability to rise from a sitting position on the floor is also a strong predictor of longevity.

For the new study, the researchers assessed 1,702 people in Brazil (68% men) aged 51-75 years who had been participating in an ongoing exercise study that began there in 1994.
 

Three tries to succeed

Starting in 2008, the team introduced the standing test, which involves balancing on one leg and placing the other foot at the back weight-bearing limb for support. People get three tries to maintain that posture for at least 10 seconds.

Not surprisingly, the ability to perform the test dropped with age. Although 20% of people in the study overall were unable to stand on one leg for 10 seconds, that figure rose to about 70% for those aged 76-80 years, and nearly 90% for those aged 81-85, according to the researchers. Of the two dozen 85-year-olds in the study, only two were able to complete the standing test, Dr. Araújo told this news organization.

At roughly age 70, half of people could not complete the 10-second test.

Over an average of 7 years of follow-up, 17.5% of people who could not manage the 10-second stand had died, compared with 4.5% of those who could last that long, the study found.

After accounting for age and many other risk factors, such as diabetes, body mass index, and a history of heart disease, people who were unable to complete the standing test were 84% more likely to die from any cause over the study period than their peers with better one-legged static balance (95% confidence interval, 1.23-2.78; P < .001).

The researchers said their study was limited by its lack of diversity – all the participants were relatively affluent Brazilians – and the inability to control for a history of falls and physical activity. But they said the size of the cohort, the long follow-up period, and their use of sophistical statistical methods helped mitigate the shortcomings.

Although low aerobic fitness is a marker of poor health, much less attention has been paid to nonaerobic fitness – things like balance, flexibility, and muscle strength and power, Dr. Araújo said.

“We are accumulating evidence that these three components of nonaerobic physical fitness are potentially relevant for good health and even more relevant for survival in older subjects,” Dr. Araújo said. Poor nonaerobic fitness, which is normally but not always associated with a sedentary lifestyle, “is the background of most cases of frailty, and being frail is strongly associated with a poor quality of life, less physical activity and exercise, and so on. It’s a bad circle.”

Dr. Araújo’s group has been using the standing test in their clinic for more than a dozen years and have seen gains in their patients. “Patients are often unaware that they are unable to sustain 10 seconds standing one legged. After this simple evaluation, they are much more prone to engage in balance training,” he said.

For now, the researchers don’t have data to show that improving static balance or performance on the standing test can affect survival, a “quite attractive” possibility, he added. But balance can be substantially improved through training.

“After only a few sessions, an improvement can be perceived, and this influences quality of life,” Dr. Araújo said. “And this is exactly what we do with the patients that we evaluated and for those that are attending our medically supervised exercise program.”

George A. Kuchel, MD, CM, FRCP, professor and Travelers Chair in Geriatrics and Gerontology at the University of Connecticut, Farmington, called the research “well done” and said the results “make perfect sense, since we have known for a long time that muscle strength is an important determinant of health, independence, and survival.”

Identifying frail patients quickly, simply, and reliably in the clinical setting is a pressing need, Dr. Kuchel, director of the UConn Center on Aging, said in an interview. The 10-second test “has considerable appeal” for this purpose.

“This could be, or rather should be, of great interest to all busy clinicians who see older adults in primary care or consultative capacities,” Dr. Kuchel added. “I hate to be nihilistic as regards what is possible in the context of really busy clinical practices, but even the minute or so that this takes to do may very well be too much for busy clinicians to do.”

Dr. Araújo and Dr. Kuchel reported no relevant financial relationships.

A U.S. Food and Drug Administration advisory panel has rejected the atypical antipsychotic pimavanserin (Nuplazid, Acadia Pharmaceuticals) for the treatment of Alzheimer’s disease psychosis (ADP).

In a 9-3 vote, the Psychopharmacologic Drugs Advisory Committee (PDAC) found that the drug’s manufacturer failed to offer convincing evidence of its efficacy in patients with ADP.

The June 17 rejection was the second rejection in as many years for a new indication for pimavanserin, which was approved in 2016 for Parkinson’s disease psychosis (PDP).

In April 2021, the FDA denied Acadia’s supplemental new drug application to expand the drug’s indication to include the treatment of all dementia-related psychosis, regardless of the underlying cause of dementia, citing issues with two studies the company presented as evidence of efficacy.

Lack of efficacy

Pimavanserin is a selective serotonin inverse agonist and antagonist preferentially targeting 5-HT2A receptors, which are thought to play an important role in psychosis, schizophrenia, depression, and other neuropsychiatric disorders.

When it rejected Acadia’s original, broader application for pimavanserin for all dementia-related psychosis, the FDA found that the HARMONY phase 3 trial, previously covered by this news organization, was underpowered to assess efficacy in specific dementia patient subgroups and lacked statistical significance of efficacy in patients with AD. In addition, it noted that overall findings appeared to be driven by results in patients with Parkinson’s disease dementia, a condition already covered by the approved indication.

The FDA found that the second study, referred to in the June 17 hearing as Study 019, which was also previously reported by this news organization, was not “an adequate and well-controlled study.”

Specifically, the agency raised concerns about “protocol deviations,” such as the inclusion of patients who lacked clear documentation that psychotic symptoms developed after an AD diagnosis had been established and patients who received exclusionary medications at the time of randomization.

Discussions between Acadia and the FDA continued over the past year, with the company submitting new analyses and responses. An FDA briefing document published in advance of the committee meeting seemed to suggest the agency was satisfied with Acadia’s response.
 

Lack of diversity

The advisory committee disagreed, pointing to the same concerns raised last year. Members raised concerns about patient diversity in the HARMONY trial, which included an almost entirely White and mostly male study population.

In addition, although the findings at 26 weeks did demonstrate a marked improvement in psychosis symptoms overall, committee members noted that, again, those findings were largely driven by efficacy in patients with Parkinson’s disease dementia, for which the drug is already approved.

When discussing the phase 2 Study 019, the committee noted that while the study met the primary outcome of improvement in psychosis at 6 weeks, those positive responses were not found at any other timepoint in the 12-week study.  

“While it might have had a positive numerical effect in the study, the evidence is really not there to support it,” Dr. Follmann said.

Dr. Follmann and other committee members called for additional trials that focus on patients with Alzheimer’s disease, have a longer follow-up, and include more gender and racial diversity in the study population. They also called for more information about any off-label use of pimavanserin for ADP since it was approved for PDP in 2016.
 

An unmet need

Most individuals who testified during the public comment period pleaded with the committee to vote in favor of the new indication, sharing stories of family members and patients with ADP.

“I have been caring for and studying patients with Alzheimer’s disease and other dementias for more than 30 years, and I can tell you very simply that if left untreated, psychosis has significant and sometimes devastating consequences for our patients,” said Pierre Tariot, MD, director of the Banner Alzheimer’s Institute and a research professor of psychiatry at the University of Arizona College of Medicine, Tucson, and an investigator on the HARMONY trial.

Those on the committee who voted against the application were quick to agree that lack of an approved treatment for ADP presents a hardship.

“I’m a neurologist who has cared for patients for more than 20 years,” said Madhav R. Thambisetty, MD, PhD, senior investigator for the National Institute on Aging and an adjunct professor of neurology at Johns Hopkins University School of Medicine, Baltimore. “I recognize the unmet need in the field, I just think that the unmet need should not be a justification to cut corners.”

The committee did not focus on drug safety or unmet need in its deliberations, although information on both were presented during the meeting.

Commenting on his “no” vote, PDAC member Walter S. Dunn, MD, PhD, assistant clinical professor of psychiatry at the University of California, Los Angeles, and director of Interventional Psychiatry Service at West Los Angeles Veterans Affairs Medical Center, said he hopes that the FDA will consider those issues more broadly as they complete their review.

“The questions before the committee have been narrow and precise, so I trust the agency will take a broader approach in their final decision about approval,” Dr. Dunn said.

Commenting on the decision, Howard Fillit, MD, cofounder and chief science officer, Alzheimer’s Drug Discovery Foundation, called the news disappointing, “but while the unmet need for a treatment for ADP is clear, it is vital that approved treatments meet stringent safety and efficacy criteria so we can offer patients medications with clear benefits.”

The FDA will make its final decision by August 4.

The following highlights are a brief overview of guideline updates, drug approvals, and diagnostics relevant to geriatric medicine from June 2021 to April 2022, some of which were discussed at the American Geriatrics Society conference in May. I selected these topics as they were among the most discussed by my colleagues in geriatric medicine and inquired about by my primary care patients in geriatric medicine clinic. I hope that these updates provide primary care clinicians who care for older adults with more context and background information regarding new Alzheimer’s disease therapy to better answer patient inquiries, and to feel empowered to deprescribe aspirin and reframe the diagnostic criteria of chronic kidney disease (CKD).

Aspirin for primary prevention

It was welcome news in the geriatrics community when the United States Preventive Services Task Force updated their guidelines in April 2022 to recommend against the initiation of aspirin for primary prevention in adults aged 60 or older. This recommendation was based on studies that found that net benefits of CVD prevention in older adults are outweighed by risk of bleeding.¹

The risk of bleeding increases with age and can occur in individuals without common risk factors for bleeding, such as prior gastrointestinal bleeding, peptic ulcer disease, concurrent NSAID use, or corticosteroid use.

While it may be easier to not initiate aspirin for primary prevention, deprescribing aspirin for patients who have been on aspirin long term for primary prevention presents more of a challenge. Modeling data from the USPTSF suggest stopping aspirin at age 75 for those taking aspirin for primary prevention.²

Behavioral change, particularly for patients who have been on aspirin for decades, can be difficult. A 2021 study by Green et al. found that language that resonates the most with older adults when deprescribing emphasized the side effects rather than statements such as “this will not help you” or “do not need anymore.”3
 

Aducanumab for mild cognitive impairment and mild Alzheimer’s dementia

One of the most discussed topics this past year is the Food and Drug Administration approval of aducanumab (brand name Aduhelm) in June 2021. Aducanumab is the first approved disease-modifying therapy for Alzheimer’s disease and the first drug approved for the treatment of Alzheimer’s disease since 2003. Aducanumab is an antiamyloid monoclonal antibody that was developed to reduce amyloid plaque in the brain, one of the features of Alzheimer’s disease pathology.

Uptake of aducanumab by dementia providers has been limited for several reasons. Firstly, the clinical significance of the drug remains in question. ENGAGE and EMERGE were the two main randomized clinical trials that studied the effect of aducanumab on amyloid burden and clinical stages of dementia over 18 months. While both studies demonstrated that aducanumab reduced amyloid burden based on neuroimaging and in cerebrospinal fluid, the ENGAGE trial found no difference in the stage of dementia. The EMERGE trial did note a small, statistically significant difference in stage of dementia, however the participants of the EMERGE trial had a faster rate of progression of dementia than the placebo participants in the ENGAGE trial, which could have contributed to the difference detected.⁴

Additionally, exclusion criteria for both trials call into question the generalizability of this study. Participants over age 85, with CKD, prior stroke, or transient ischemic attacks, or on anticoagulation were excluded. One of the drivers for the exclusion criteria is the increased risk of macro and microhemorrhages.

Thirty-five percent of research participants were incidentally noted to have brain edema, an abnormality called amyloid-related imaging abnormality or ARIA-E, that necessitated serial monitoring with brain MRIs. It is also important to highlight that inclusion of African American, Hispanic, and Latinx participants in these studies was less than 5%, despite a higher incidence of Alzheimer’s disease in these populations.⁵

Lastly, economic implications for the U.S. health care system with increased uptake of aducanumab could be enormous. Originally quoted at $56,000 yearly, Biogen, the maker of aducanumab, recently reduced annual costs to $28,200 per patient.

In April 2022, CMS released a statement that antiamyloid monoclonal antibodies and related services, including PET scans, would be covered under Medicare for those with mild cognitive impairment and mild Alzheimer’s dementia with confirmed presence of amyloid. A study by Mafi et al. estimated that aducanumab could cost Medicare between $7 billion and $37.4 billion annually based on lower and upper bound estimates of eligible Medicare beneficiaries.⁶
 

Overdiagnosis of CKD in older adults

The current diagnostic criteria of CKD, which is based on an estimated glomerular filtration rate (eGFR) of less than 60, has been up for debate, as glomerular filtration rate (GFR) physiologically decreases with age. Fixed thresholds can lead to underdiagnosis of CKD in younger adults and overdiagnosis of CKD in older adults. Age-adapted thresholds for the diagnosis of CKD have been proposed, with the suggestion of an eGFR threshold of 45mL/min/1.73 m² for adults aged 65 and older.⁷

The clinical implication of using an age-adapted eGFR threshold definition was investigated in a 2021 cohort study by Liu et al.⁸ In this study, outcomes of adults diagnosed with CKD using a fixed threshold versus age-adapted threshold were compared with a healthy cohort.

A fixed threshold led to a 60% higher incidence of CKD diagnosis. However, incidence of renal failure and all-cause mortality in older adults with an eGFR between 45-59 /min/1.73 m2 with normal or mild albuminuria was of similar magnitude to the healthy cohort at 5 years of follow-up.

These findings support the use of age-adapted thresholds for the diagnosis of CKD in older adults, as an earlier diagnosis of mild CKD does not equate to clinical benefits, but could lead to harms of unnecessary interventions and patient anxiety.

A study of elderly patients with HER2-positive/HR-negative metastatic breast cancer finds a significantly shorter median overall survival in actual clinical practice than younger counterparts.

After 46 months of treatment, the survival rate was only 25%, according to a study presented in June at the annual meeting of the American Society of Clinical Oncology. The finding suggests that older age is an important prognostic factor for breast cancer survival, said study author Zhonghui Jenny Ou, a doctoral candidate at the Massachusetts College of Pharmacy and Health Sciences in Boston.

For comparison, Ms. Ou cited the CLEOPATRA trial which showed a median overall survival of 57.1 months for patients who were treated with pertuzumab, docetaxel and trastuzumab versus 40.8 months for placebo with docetaxel plus trastuzumab.

The Ou study is based on an analysis of data between 2012 and 2016 from the SEER-Medicare database. The final analysis included 73 women (average age 75 years at diagnosis) with early-stage HER2-positive/HR-negative metastatic breast cancer. Fifty-six women were treated with trastuzumab with pertuzumab and chemotherapy as first-line treatment, and 17 were treated with chemotherapy only. The longest length of treatment with trastuzumab was over 44 months. And, the median follow-up for overall survival was 13 months (95% confidence interval, 12.7-18.7).

Between 2012 and 2016, five patients died from other causes, including lung cancer, cerebrovascular diseases, aortic aneurysm and dissection, pneumonia and influenza, and heart disease.

“While there are many clinical trials about HER2-positive metastatic breast cancer, these trials were all performed in younger and relatively healthier patients. Few studies included elderly patients 65 years or older,” Ms. Ou said.

According to the American Cancer Society, 31% of all newly diagnosed breast cancer cases are in women who are 70 years old or older, yet 47% of all breast cancer deaths each year are in women in this age group.

Undertreatment and lower treatment intensity have been cited by other studies as possible contributing factors to lower overall survival rates, but breast cancer in elderly women is a complex and understudied subject. Why the mortality rates for elderly women are disproportionately higher than those of younger women is attributable to a number of reasons, write the authors of one of the most recent studies on the subject.

“It is well established that receipt of adjuvant chemotherapy, trastuzumab, and hormonal therapy reduces risk of recurrence and death across all age groups, yet multiple studies document suboptimal systemic treatment and adherence for older patients, including omission of efficacious treatments, receipt of lower intensity and/or nonguideline treatment, or poor adherence to hormonal therapy,” Freedman et al. wrote in the May 15, 2018, issue of the journal Cancer.

While the Ou study sample size was small, the study’s real-world analysis is telling, Ms. Ou said.

“The major limitation of this study is that it has – after applying all the eligibility criteria to the 170,516 breast cancer patients from the SEER-Medicare database between 2012 and 2016 – a study population of just 73 patients. The number is sufficient to do survival analysis,” she said.

I enjoyed reading “How to identify balance disorders and reduce fall risk” (J Fam Pract. 2022;71:20-30) from the January/February issue. I was, however, disappointed to see that normal pressure hydrocephalus (NPH) was not discussed in the article or tables.

Recently, I took care of a 72-year-old patient who presented after multiple falls. In conjunction with Neurology, the presumptive diagnosis of Parkinson disease was made. However, the patient continued to experience a health decline that included cognitive changes, nocturia, and the classic “magnetic gait” of NPH (mnemonic for diagnosing this triad of symptoms: weird, wet, wobbly). The presumptive diagnosis was then changed when the results of a fluorodopa F18 positron emission tomography scan (also known as a DaT scan) returned as normal, essentially excluding the diagnosis of Parkinson disease.

The patient has since seen a dramatic improvement in gait and cognitive and urinary symptoms following a high-volume lumbar puncture and placement of a ventriculoperitoneal shunt. 

This case demonstrates the importance of considering NPH in the differential diagnosis for patients with balance disorders. Prompt diagnosis and management can result in a variable, but at times dramatic, reversal of symptoms.

I enjoyed reading “How to identify balance disorders and reduce fall risk” (J Fam Pract. 2022;71:20-30) from the January/February issue. I was, however, disappointed to see that normal pressure hydrocephalus (NPH) was not discussed in the article or tables.

THE CASE

A 78-year-old woman with a past medical history of hypertension, hyperlipidemia, osteoarthritis, and osteopenia was brought to the emergency department (ED) by her daughter. The woman had fallen 2 days earlier and had been experiencing a change in mental status (confusion) for the previous 4 days. Prior to her change in mental status, the patient had been independent in all activities of daily living and instrumental activities of daily living.

Her daughter could not recall any symptoms of illness; new or recently changed medications; complaints of pain, constipation, diarrhea, urinary frequency, or hematuria; or changes in continence prior to the onset of her mother’s confusion.

The patient’s medications included amlodipine, atorvastatin, calcium/vitamin D, and acetaminophen (as needed). In the ED, her vital signs were normal, and her cardiopulmonary and abdominal exams were unremarkable. A limited neurologic exam showed that the patient was oriented only to person and could not answer questions about her symptoms or follow commands. She could move all of her extremities equally and could ambulate; she had no facial asymmetry or slurred speech. Her exam was negative for orthostatic hypotension.

Her complete blood count, comprehensive metabolic panel, and troponin levels were normal. Her electrocardiogram showed normal sinus rhythm with no abnormalities. X-rays of her right hip and elbow were negative for fracture. Computed tomography of her head was negative for acute findings, and a chest x-ray was normal.

Her urinalysis showed many bacteria and large leukocyte esterase, and a urine culture was sent out. She was hemodynamically stable and there were no known urinary symptoms, so no empiric antibiotics were started. She was admitted for further evaluation of her altered mental status (AMS).

On our service, she was given intravenous fluids, and oral intake was encouraged. She had normal levels of B12, folic acid, and thyroid-stimulating hormone. She was negative for HIV and syphilis. Acute coronary syndrome was ruled out with normal electrocardiograms and troponin levels. Her telemetry showed a normal sinus rhythm.

After 2 days, her vital signs and labs remained stable and no other abnormalities were found; however, she had not returned to her baseline mental status. Then the urine culture returned with > 10⁵ CFU/mL of Escherichia coli, prompting a resident to curbside me (AP) and ask: “I shouldn’t treat this patient based on her urine culture—she’s just colonized, right? Or should I treat her because she’s altered?”

Continue to: THE CHALLENGE

Identifying and managing urinary tract infections (UTIs) in older adults often presents a challenge, further complicated if patients have AMS or cognitive impairment and are unable to confirm or deny urinary symptoms.

Consider, for instance, the definition of symptomatic UTI: significant bacteriuria (≥ 10⁵ CFU/mL) and pyuria (> 10 WBC/hpf) with UTI-specific symptoms (fever, acute dysuria, new or worsening urgency or frequency, new urinary incontinence, gross hematuria, and suprapubic or costovertebral angle pain or tenderness).¹ In older adults, these parameters require a more careful look.

For instance, while we use the cutoff of ≥ 10⁵ CFU/mL to define “significant” bacteriuria, the truth is that we don’t know the colony count threshold that can help identify patients who are at risk of serious illness and might benefit from antibiotic treatment.²

After reviewing the culture results, clinicians then face 2 specific challenges: differentiating between acute vs chronic symptoms and related vs unrelated symptoms in the older adult population.

Challenge 1: There is a high prevalence of chronic genitourinary symptoms in older adults that can sometimes make it hard to distinguish between an acute UTI and the acute recognition of a chronic, non-UTI problem.¹

Continue to: Challenge 2

Challenge 2: There is a high prevalence of multimorbidity in older adults. For instance, diuretics for heart failure can cause UTI-specific symptoms such as urinary urgency, frequency, and even incontinence. Cognitive impairment can make it difficult to obtain the key components of the history needed to make a UTI diagnosis.¹

Lastly, there are aspects of normal aging physiology that complicate the detection of infections, such as the fact that older adults may not mount a “true” fever to meet criteria for a symptomatic UTI. Therefore, fever in institutionalized or frail community-dwelling older adults has been redefined as an oral temperature ≥ 100 °F, 2 repeated oral temperatures > 99 °F, or an increase in temperature ≥ 2 °F from baseline.³

So how to proceed with our case patient? The following questions helped guide the approach to her care.

Is this patient asymptomatic?

Yes. The patient presented with nonspecific symptoms (falls and delirium) with bacteriuria suggesting asymptomatic bacteriuria (ASB). These symptoms are referred to as geriatric syndromes that, by definition, are “multifactorial health conditions that occur when the accumulated effects of impairments in multiple systems render an older person vulnerable to situational challenges.”⁴

There are aspects of normal aging physiology that complicate the detection of infections, such as the fact that older adults may not mount a “true” fever to meet criteria for a symptomatic UTI.

As geriatric syndromes, falls and delirium are unlikely to be caused by one process, such as a UTI, but rather from multiple morbid processes. It is also important to note that there is no evidence to support a causal relationship between bacteriuria and delirium or that antibiotic treatment of bacteriuria improves delirium.^2,5

Continue to: So, while we could...

So, while we could have diagnosed a UTI in this older adult with bacteriuria and delirium, it would have been premature closure and an incomplete assessment. We would have risked potentially missing other significant causes of her delirium and unnecessarily exposing the patient to antibiotics.

Are antibiotics generally useful in older adults who you believe to be asymptomatic with a urine culture showing bacteriuria?

No. The goal of antibiotic treatment for a symptomatic UTI is to ameliorate symptoms; therefore, there is no indication for antibiotics in ASB and no evidence of survival benefit.² And, as noted earlier, there is no evidence to support a causal relationship between bacteriuria and delirium or that antibiotic treatment of bacteriuria improves delirium.^2,5

The use of antibiotics in the asymptomatic setting will eradicate any bacteriuria but also increase the risk of reinfection, resistant organisms, antibiotic adverse reactions, and medication interactions.¹

What is the recommendation for management of nonspecific symptoms, such as delirium and falls, in a geriatric patient such as this one with bacteriuria?

The Infectious Diseases Society of America (IDSA)’s 2019 Clinical Practice Guideline for the Management of Asymptomatic Bacteriuria recommends a thorough assessment (for other causes) and careful observation, rather than immediate antimicrobial treatment and cessation of evaluation for other causes.⁵ (IDSA made this recommendation based on low-quality evidence.) The group found a high certainty of harm and low certainty of benefit in treating older adults with antibiotics for ASB.

This recommendation highlights the key geriatric principle of “geriatric syndromes” and the multifactorial nature of findings such as delirium and falls. It encourages clinicians to continue their thorough assessment for other causes in addition to bacteriuria.⁵ Even in the event that antibiotics are immediately initiated, we would recommend avoiding premature closure and continuing to evaluate for other causes.

Continue to: It is reasonable to...

It is reasonable to obtain a dipstick if, after the observation period (1-7 days, with earlier follow-up for frail patients), the patient continues to have the nonspecific symptoms.¹ If the dipstick is negative, there is no need for further evaluation of UTI. If it’s positive, then it’s appropriate to send for urinalysis and urine culture.¹

I emphasized that we were treating bacteriuria with persisting delirium without any other etiology identified.

If the urine culture is negative, continue looking for other etiologies. If it’s positive, but there is resolution of symptoms, there is no need to treat. If it’s positive and symptoms persist, consider antibiotic treatment.¹

CASE RESOLUTION

The team closely monitored the patient and delayed empiric antibiotics while continuing the AMS work-up. After 2 days in the hospital, her delirium persisted, but she had no UTI-specific symptoms and she remained hemodynamically stable.

I (AP) recommended antibiotic treatment guided by the urine culture sensitivity report: initially 1 g of ceftriaxone IV q24h with transition (after symptom improvement and prior to discharge) to oral trimethoprim/sulfamethoxazole 160 mg/800 mg q12h, for a total of 10 days of treatment. I emphasized that we were treating bacteriuria with persisting delirium without any other etiology identified. The patient returned to her baseline mental status after a few days of treatment and was discharged home.

THE TAKEAWAY

Avoid premature closure by stopping at the diagnosis of a “UTI” in an older adult with nonspecific symptoms and bacteriuria to avoid the risk of overlooking other important and potentially life-threatening causes of the patient’s signs and symptoms.

Opioid use in the elderly is associated with an almost 40% increased risk of dementia in new findings that suggest exposure to these drugs may be another modifiable risk factor for dementia.

“Clinicians and others may want to consider that opioid exposure in those aged 75-80 increases dementia risk, and to balance the potential benefits of opioid use in old age with adverse side effects,” said Stephen Z. Levine, PhD, professor, department of community mental health, University of Haifa (Israel).

The study was published online in the American Journal of Geriatric Psychiatry.
 

Widespread use

Evidence points to a relatively high rate of opioid prescriptions among older adults. A Morbidity and Mortality Weekly Report noted 19.2% of the U.S. adult population filled an opioid prescription in 2018, with the rate in those over 65 double that of adults aged 20-24 years (25% vs. 11.2%).

Disorders and illnesses for which opioids might be prescribed, including cancer and some pain conditions, “are far more prevalent in old age than at a younger age,” said Dr. Levine.

This high rate of opioid use underscores the need to consider the risks of opioid use in old age, said Dr. Levine. “Unfortunately, studies of the association between opioid use and dementia risk in old age are few, and their results are inconsistent.”

The study included 91,307 Israeli citizens aged 60 and over without dementia who were enrolled in the Meuhedet Healthcare Services, a nonprofit health maintenance organization (HMO) serving 14% of the country’s population. Meuhedet has maintained an up-to-date dementia registry since 2002.

The average age of the study sample was 68.29 years at the start of the study (in 2012).

In Israel, opioids are prescribed for a 30-day period. In this study, opioid exposure was defined as opioid medication fills covering 60 days (or two prescriptions) within a 120-day interval.

The primary outcome was incident dementia during follow-up from Jan. 1, 2013 to Oct. 30, 2017. The analysis controlled for a number of factors, including age, sex, smoking status, health conditions such as arthritis, depression, diabetes, osteoporosis, cognitive decline, vitamin deficiencies, cancer, cardiovascular conditions, and hospitalizations for falls.

Researchers also accounted for the competing risk of mortality.

During the study, 3.1% of subjects were exposed to opioids at a mean age of 73.94 years, and 5.8% of subjects developed dementia at an average age of 78.07 years.
 

Increased dementia risk

The risk of incident dementia was significantly increased in those exposed to opioids versus unexposed individuals in the 75- to 80-year age group (adjusted hazard ratio, 1.39; 95% confidence interval, 1.01-1.92; z statistic = 2.02; P < .05).

The authors noted the effect size for opioid exposure in this elderly age group is like other potentially modifiable risk factors for dementia, including body mass index and smoking.

The current study could not determine the biological explanation for the increased dementia risk among older opioid users. “Causal notions are challenging in observational studies and should be viewed with caution,” Dr. Levine noted.

However, a plausible mechanism highlighted in the literature is that opioids promote apoptosis of microglia and neurons that contribute to neurodegenerative diseases, he said.

The study included 14 sensitivity analyses, including those that looked at females, subjects older than 70, smokers, and groups with and without comorbid health conditions. The only sensitivity analysis that didn’t have similar findings to the primary analysis looked at dementia risk restricted to subjects without a vitamin deficiency.

“It’s reassuring that 13 or 14 sensitivity analyses found a significant association between opioid exposure and dementia risk,” said Dr. Levine.

Some prior studies did not show an association between opioid exposure and dementia risk. One possible reason for the discrepancy with the current findings is that the previous research didn’t account for age-specific opioid use effects, or the competing risk of mortality, said Dr. Levine.

Clinicians have a number of potential alternatives to opioids to treat various conditions including acetaminophen, non-steroidal anti-inflammatory drugs, amine reuptake inhibitors (ARIs), membrane stabilizers, muscle relaxants, topical capsaicin, botulinum toxin, cannabinoids, and steroids.

A limitation of the study was that it didn’t adjust for all possible comorbid health conditions, including vascular conditions, or for use of benzodiazepines, and surgical procedures.

In addition, since up to 50% of dementia cases are undetected, it’s possible some in the unexposed opioid group may actually have undiagnosed dementia, thereby reducing the effect sizes in the results.

Reverse causality is also a possibility as the neuropathological process associated with dementia could have started prior to opioid exposure. In addition, the results are limited to prolonged opioid exposure.
 

Interpret with caution

Commenting on the study, David Knopman, MD, a neurologist at Mayo Clinic in Rochester, Minn., whose research involves late-life cognitive disorders, was skeptical.

“On the face of it, the fact that an association was seen only in one narrow age range – 75+ to 80 years – ought to raise serious suspicion about the reliability and validity of the claim that opioid use is a risk factor for dementia, he said.

Although the researchers performed several sensitivity analyses, including accounting for mortality, “pharmacoepidemiological studies are terribly sensitive to residual biases” related to physician and patient choices related to medication use, added Dr. Knopman.

The claim that opioids are a dementia risk “should be viewed with great caution” and should not influence use of opioids where they’re truly indicated, he said.

“It would be a great pity if patients with pain requiring opioids avoid them because of fears about dementia based on the dubious relationship between age and opioid use.”

Opioid use in the elderly is associated with an almost 40% increased risk of dementia in new findings that suggest exposure to these drugs may be another modifiable risk factor for dementia.

“Clinicians and others may want to consider that opioid exposure in those aged 75-80 increases dementia risk, and to balance the potential benefits of opioid use in old age with adverse side effects,” said Stephen Z. Levine, PhD, professor, department of community mental health, University of Haifa (Israel).

The study was published online in the American Journal of Geriatric Psychiatry.
 

Widespread use

Evidence points to a relatively high rate of opioid prescriptions among older adults. A Morbidity and Mortality Weekly Report noted 19.2% of the U.S. adult population filled an opioid prescription in 2018, with the rate in those over 65 double that of adults aged 20-24 years (25% vs. 11.2%).

Disorders and illnesses for which opioids might be prescribed, including cancer and some pain conditions, “are far more prevalent in old age than at a younger age,” said Dr. Levine.

This high rate of opioid use underscores the need to consider the risks of opioid use in old age, said Dr. Levine. “Unfortunately, studies of the association between opioid use and dementia risk in old age are few, and their results are inconsistent.”

The study included 91,307 Israeli citizens aged 60 and over without dementia who were enrolled in the Meuhedet Healthcare Services, a nonprofit health maintenance organization (HMO) serving 14% of the country’s population. Meuhedet has maintained an up-to-date dementia registry since 2002.

The average age of the study sample was 68.29 years at the start of the study (in 2012).

In Israel, opioids are prescribed for a 30-day period. In this study, opioid exposure was defined as opioid medication fills covering 60 days (or two prescriptions) within a 120-day interval.

The primary outcome was incident dementia during follow-up from Jan. 1, 2013 to Oct. 30, 2017. The analysis controlled for a number of factors, including age, sex, smoking status, health conditions such as arthritis, depression, diabetes, osteoporosis, cognitive decline, vitamin deficiencies, cancer, cardiovascular conditions, and hospitalizations for falls.

Researchers also accounted for the competing risk of mortality.

During the study, 3.1% of subjects were exposed to opioids at a mean age of 73.94 years, and 5.8% of subjects developed dementia at an average age of 78.07 years.
 

Increased dementia risk

The risk of incident dementia was significantly increased in those exposed to opioids versus unexposed individuals in the 75- to 80-year age group (adjusted hazard ratio, 1.39; 95% confidence interval, 1.01-1.92; z statistic = 2.02; P < .05).

The authors noted the effect size for opioid exposure in this elderly age group is like other potentially modifiable risk factors for dementia, including body mass index and smoking.

The current study could not determine the biological explanation for the increased dementia risk among older opioid users. “Causal notions are challenging in observational studies and should be viewed with caution,” Dr. Levine noted.

However, a plausible mechanism highlighted in the literature is that opioids promote apoptosis of microglia and neurons that contribute to neurodegenerative diseases, he said.

The study included 14 sensitivity analyses, including those that looked at females, subjects older than 70, smokers, and groups with and without comorbid health conditions. The only sensitivity analysis that didn’t have similar findings to the primary analysis looked at dementia risk restricted to subjects without a vitamin deficiency.

“It’s reassuring that 13 or 14 sensitivity analyses found a significant association between opioid exposure and dementia risk,” said Dr. Levine.

Some prior studies did not show an association between opioid exposure and dementia risk. One possible reason for the discrepancy with the current findings is that the previous research didn’t account for age-specific opioid use effects, or the competing risk of mortality, said Dr. Levine.

Clinicians have a number of potential alternatives to opioids to treat various conditions including acetaminophen, non-steroidal anti-inflammatory drugs, amine reuptake inhibitors (ARIs), membrane stabilizers, muscle relaxants, topical capsaicin, botulinum toxin, cannabinoids, and steroids.

A limitation of the study was that it didn’t adjust for all possible comorbid health conditions, including vascular conditions, or for use of benzodiazepines, and surgical procedures.

In addition, since up to 50% of dementia cases are undetected, it’s possible some in the unexposed opioid group may actually have undiagnosed dementia, thereby reducing the effect sizes in the results.

Reverse causality is also a possibility as the neuropathological process associated with dementia could have started prior to opioid exposure. In addition, the results are limited to prolonged opioid exposure.

As increasing numbers of patients in their 80s, 90s, and even 100s present for possible Mohs micrographic surgery, surgeons are confronted with deciding when the risks of treatment may outweigh the benefits.

In one of two presentations at the annual meeting of the American College of Mohs Surgery that addressed this topic, Howard W. Rogers, MD, of Advanced Dermatology in Norwich, Conn., said that the crux of the issue is the concern not to undertreat. He noted that reduced access to dermatologic care during the pandemic has provided a stark lesson in the risks of delaying treatment in all age groups. “Mohs surgeons have all seen the consequences of delayed treatment due to the pandemic with enormous, destructive, and sometimes fatal cancers coming to the office in the last year,” he told this news organization.

“Pandemic-related treatment delay has caused increased suffering and morbidity for countless skin cancer patients across the U.S.,” he said. “In general, not treating skin cancer and hoping it’s not going to grow or having significant delays in treatment are a recipe for disastrous outcomes.”

That said, active monitoring may be appropriate “for select small cancers that tend to grow slowly in the very elderly,” added Dr. Rogers, the incoming ACMS president. Among the key situations where the benefits of active monitoring may outweigh the risks of surgery are small, slowly growing cancers, when frailty is an issue.

Frailty has been equated to compromised functionality, which can increase the risk of an array of complications, including prolonged wound healing and secondary complications stemming from immobility. The toll those issues can take on patients’ quality of life can be considerable, Dr. Rogers said.

When weighing treatment options with elderly patients, he emphasized that careful consideration should be given to whether the “time needed to benefit from a Mohs procedure is longer than the patient’s life expectancy.” Furthermore, a decision not to treat does not have to be the last word. “We need to have an honest dialogue on the consequences of nontreatment, but part of that should be that just because we don’t treat today, doesn’t mean we can’t treat it tomorrow, if necessary.”

Of note, he added, “more than 100,00 patients have surgery for basal cell carcinoma [BCC] in their last year of life.” And that figure will likely rise exponentially if population projections come to fruition, considering that the population of people over the age of 85 is predicted to increase to nearly 18 million in 2050, from 5.8 million in 2012, Dr. Rogers said.

Until more research emerges on how to best treat this age group, Dr. Rogers noted that experts recommend that for elderly patients, “treatment should be individualized with consideration of active monitoring of primary BCC that is not in the H-zone, asymptomatic, smaller than 1 cm, with treatment initiated if there is substantial growth or symptoms.” Ultimately, he urged surgeons to “be sensitive and treat our patients like ourselves or our family members.”
 

When appropriate – Mohs is safe in the very elderly

Taking on the issue in a separate presentation, Deborah MacFarlane, MD, professor of dermatology and head and neck surgery at MD Anderson Cancer Center, Houston, said that for skin cancer cases that warrant treatment, clinicians should not let age alone stand in the way of Mohs surgery.

The evidence of its safety in the elderly dates back to a paper published in 1997 that Dr. MacFarlane coauthored, describing Mohs surgery of BCCs, squamous cell cancers (SCCs), and melanomas among 115 patients aged 90 and older (average, 92.4 years) who had an average of 1.9 comorbid medical conditions, and were taking an average of 2.3 medications. “Overall, we had just one complication among the patients,” she said.

In a subsequent paper, Dr. MacFarlane and her colleagues found that age at the time of Mohs surgery, even in older patients, was unrelated to survival, stage of cancer, or the type of repair. “We have concluded that this rapidly growing segment of the population can undergo Mohs surgery and should not be relegated to less effective treatment out of fear of its affecting their survival,” Dr. MacFarlane said.

She agreed with the concern about frailty and hence functionality, which may need to be factored in when making a decision to perform Mohs surgery. “I think this is something we do intuitively anyway,” she added. “We’re going to offer Mohs to someone who we think will survive and who is in relatively good health,” Dr. MacFarlane noted.

The point is illustrated in a new multicenter study of 1,181 patients at 22 U.S. sites, aged 85 years and older with nonmelanoma skin cancer referred for Mohs surgery. In the study, published in JAMA Dermatology after the ACMS meeting, patients who had Mohs surgery were almost four times more likely to have high functional status (P < .001) and were more likely to have facial tumors (P < .001), compared with those who had an alternate surgery.

The main reasons provided by the surgeons for opting to treat with Mohs included a patient’s desire for treatment with a high cure rate (66%), good/excellent patient functional status for age (57%), and a high risk associated with the tumor based on histology (40%), noted Dr. MacFarlane, one of the authors.

She reiterated the point raised by Dr. Rogers that “this is something we’re going to increasingly face,” noting that people over 85 represent the fastest growing segment of the population. “I have more patients over the age of 100 than I’ve ever had before,” she said.

Nevertheless, her own experience with elderly patients speaks to the safety of Mohs surgery in this population: Dr. MacFarlane reported a review of her practice’s records of 171 patients aged 85 years and older between May 2016 and May 2022, who received 414 separate procedures, without a single complication.

Sharing many of Dr. Rogers’ concerns about using caution in at-risk patients, Dr. MacFarlane offered recommendations for the optimal treatment of elderly patients receiving Mohs, including handling tissue delicately, and “keep undermining to a minimum.” She noted that intermediate closures and full thickness skin grafts are ideal closures for the elderly, while flaps may be performed in selected robust skin. It is also important to involve caretakers from the onset, talk and listen to patients – and play their choice of music during treatment, she said.

Commenting on the debate, comoderator Nahid Y. Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

The combination of hearing loss and vision loss is linked to an eightfold increased risk of cognitive impairment, new research shows.

Investigators analyzed data on more than 5 million U.S. seniors. Adjusted results show that participants with hearing impairment alone had more than twice the odds of also having cognitive impairment, while those with vision impairment alone had more than triple the odds of cognitive impairment.

However, those with dual sensory impairment (DSI) had an eightfold higher risk for cognitive impairment.

In addition, half of the participants with DSI also had cognitive impairment. Of those with cognitive impairment, 16% had DSI, compared with only about 2% of their peers without cognitive impairment.

“The findings of the present study may inform interventions that can support older people with concurrent sensory impairment and cognitive impairment,” said lead author Esme Fuller-Thomson, PhD, professor, Factor-Inwentash Faculty of Social Work, University of Toronto.

“Special attention, in particular, should be given to those aged 65-74 who have serious hearing and/or vision impairment [because], if the relationship with dementia is found to be causal, such interventions can potentially mitigate the development of cognitive impairment,” said Dr. Fuller-Thomson, who is also director of the Institute for Life Course and Aging and a professor in the department of family and community medicine and faculty of nursing, all at the University of Toronto.

The findings were published online in the Journal of Alzheimer’s Disease  Reports.
 

Sensory isolation

Hearing and vision impairment increase with age; it is estimated that one-third of U.S. adults between the ages of 65 and 74 experience hearing loss, and 4% experience vision impairment, the investigators note.

“The link between dual hearing loss and seeing loss and mental health problems such as depression and social isolation have been well researched, but we were very interested in the link between dual sensory loss and cognitive problems,” Dr. Fuller-Thomson said.

Additionally, “there have been several studies in the past decade linking hearing loss to dementia and cognitive decline, but less attention has been paid to cognitive problems among those with DSI, despite this group being particularly isolated,” she said. Existing research into DSI suggests an association with cognitive decline; the current investigators sought to expand on this previous work.

To do so, they used merged data from 10 consecutive waves from 2008 to 2017 of the American Community Survey (ACS), which was conducted by the U.S. Census Bureau. The ACS is a nationally representative sample of 3.5 million randomly selected U.S. addresses and includes community-dwelling adults and those residing in institutional settings.

Participants aged 65 or older (n = 5,405,135; 56.4% women) were asked yes/no questions regarding serious cognitive impairment, hearing impairment, and vision impairment. A proxy, such as a family member or nursing home staff member, provided answers for individuals not capable of self-report.

Potential confounding variables included age, race/ethnicity, sex, education, and household income.
 

Potential mechanisms

Results showed that, among those with cognitive impairment, there was a higher prevalence of hearing impairment, vision impairment, and DSI than among their peers without cognitive impairment; in addition, a lower percentage of these persons had no sensory impairment (P < .001).

The prevalence of DSI climbed with age, from 1.5% for respondents aged 65-74 years to 2.6% for those aged 75-84 and to 10.8% in those 85 years and older.

Individuals with higher levels of poverty also had higher levels of DSI. Among those who had not completed high school, the prevalence of DSI was higher, compared with high school or university graduates (6.3% vs. 3.1% and 1.85, respectively).

After controlling for age, race, education, and income, the researchers found “substantially” higher odds of cognitive impairment in those with vs. those without sensory impairments.

“The magnitude of the odds of cognitive impairment by sensory impairment was greatest for the youngest cohort (age 65-74) and lowest for the oldest cohort (age 85+),” the investigators wrote. Among participants in the youngest cohort, there was a “dose-response relationship” for those with hearing impairment only, visual impairment only, and DSI.

Because the study was observational, it “does not provide sufficient information to determine the reasons behind the observed link between sensory loss and cognitive problems,” Dr. Fuller-Thomson said. However, there are “several potential causal mechanisms [that] warrant future research.”

The “sensory deprivation hypothesis” suggests that DSI could cause cognitive deterioration because of decreased auditory and visual input. The “resource allocation hypothesis” posits that hearing- or vision-impaired older adults “may use more cognitive resources to accommodate for sensory deficits, allocating fewer cognitive resources for higher-order memory processes,” the researchers wrote. Hearing impairment “may also lead to social disengagement among older adults, hastening cognitive decline due to isolation and lack of stimulation,” they added.

Reverse causality is also possible. In the “cognitive load on perception” hypothesis, cognitive decline may lead to declines in hearing and vision because of “decreased resources for sensory processing.”

In addition, the association may be noncausal. “The ‘common cause hypothesis’ theorizes that sensory impairment and cognitive impairment may be due to shared age-related degeneration of the central nervous system ... or frailty,” Dr. Fuller-Thomson said.
 

Parallel findings

The results are similar to those from a study conducted by Phillip Hwang, PhD, of the department of anatomy and neurobiology, Boston University, and colleagues that was published online in JAMA Network Open.

They analyzed data on 8 years of follow-up of 2,927 participants in the Cardiovascular Health Study (mean age, 74.6 years; 58.2% women).

Compared with no sensory impairment, DSI was associated with increased risk for all-cause dementia and Alzheimer’s disease, but not with vascular dementia.

“Future work in health care guidelines could consider incorporating screening of sensory impairment in older adults as part of risk assessment for dementia,” Nicholas Reed, AuD, and Esther Oh, MD, PhD, both of Johns Hopkins University, Baltimore, wrote in an accompanying editorial.
 

Accurate testing

Commenting on both studies, Heather Whitson, MD, professor of medicine (geriatrics) and ophthalmology and director at the Duke University Center for the Study of Aging and Human Development, Durham, N.C., said both “add further strength to the evidence base, which has really converged in the last few years to support that there is a link between sensory health and cognitive health.”

However, “we still don’t know whether hearing/vision loss causes cognitive decline, though there are plausible ways that sensory loss could affect cognitive abilities like memory, language, and executive function,” she said

Dr. Whitson, who was not involved with the research, is also codirector of the Duke/University of North Carolina Alzheimer’s Disease Research Center at Duke University, Durham, N.C., and the Durham VA Medical Center.

“The big question is whether we can improve patients’ cognitive performance by treating or accommodating their sensory impairments,” she said. “If safe and feasible things like hearing aids or cataract surgery improve cognitive health, even a little bit, it would be a huge benefit to society, because sensory loss is very common, and there are many treatment options,” Dr. Whitson added.

Dr. Fuller-Thomson emphasized that practitioners should “consider the full impact of sensory impairment on cognitive testing methods, as both auditory and visual testing methods may fail to take hearing and vision impairment into account.”

Thus, “when performing cognitive tests on older adults with sensory impairments, practitioners should ensure they are communicating audibly and/or using visual speech cues for hearing-impaired individuals, eliminating items from cognitive tests that rely on vision for those who are visually impaired, and using physical cues for individuals with hearing or dual sensory impairment, as this can help increase the accuracy of testing and prevent confounding,” she said.

The study by Fuller-Thomson et al. was funded by a donation from Janis Rotman. Its investigators have reported no relevant financial relationships. The study by Hwang et al. was funded by contracts from the National Heart, Lung, and Blood Institute, the National Institute of Neurological Disorders and Stroke, and the National Institute on Aging. Dr. Hwang reports no relevant financial relationships. The other investigators’ disclosures are listed in the original article. Dr. Reed received grants from the National Institute on Aging during the conduct of the study and has served on the advisory board of Neosensory outside the submitted work.

From Medically Home Group, Boston, MA.

Brick-and-mortar hospitals in the United States have historically been considered the dominant setting for providing care to patients. The coordination and delivery of care has previously been bound to physical hospitals largely because multidisciplinary services were only accessible in an individual location. While the fundamental make-up of these services remains unchanged, these services are now available in alternate settings. Some of these services include access to a patient care team, supplies, diagnostics, pharmacy, and advanced therapeutic interventions. Presently, the physical environment is becoming increasingly irrelevant as the core of what makes the traditional hospital—the professional staff, collaborative work processes, and the dynamics of the space—have all been translated into a modern digitally integrated environment. The elements necessary to providing safe, effective care in a physical hospital setting are now available in a patient’s home.

Impetus for the Model

As hospitals reconsider how and where they deliver patient care because of limited resources, the hospital-at-home model has gained significant momentum and interest. This model transforms a home into a hospital. The inpatient acute care episode is entirely substituted with an intensive at-home hospital admission enabled by technology, multidisciplinary teams, and ancillary services. Furthermore, patients requiring post-acute support can be transitioned to their next phase of care seamlessly. Given the nationwide nursing shortage, aging population, challenges uncovered by the COVID-19 pandemic, rising hospital costs, nurse/provider burnout related to challenging work environments, and capacity constraints, a shift toward the combination of virtual and in-home care is imperative. The hospital-at-home model has been associated with superior patient outcomes, including reduced risks of delirium, improved functional status, improved patient and family member satisfaction, reduced mortality, reduced readmissions, and significantly lower costs.¹ COVID-19 alone has unmasked major facility-based deficiencies and limitations of our health care system. While the pandemic is not the impetus for the hospital-at-home model, the extended stress of this event has created a unique opportunity to reimagine and transform our health care delivery system so that it is less fragmented and more flexible.

Nursing in the Model

Nursing is central to the hospital-at-home model. Virtual nurses provide meticulous care plan oversight, assessment, and documentation across in-home service providers, to ensure holistic, safe, transparent, and continuous progression toward care plan milestones. The virtual nurse monitors patients using in-home technology that is set up at the time of admission. Connecting with patients to verify social and medical needs, the virtual nurse advocates for their patients and uses these technologies to care and deploy on-demand hands-on services to the patient. Service providers such as paramedics, infusion nurses, or home health nurses may be deployed to provide services in the patient’s home. By bringing in supplies, therapeutics, and interdisciplinary team members, the capabilities of a brick-and-mortar hospital are replicated in the home. All actions that occur wherever the patient is receiving care are overseen by professional nursing staff; in short, virtual nurses are the equivalent of bedside nurses in the brick-and-mortar health care facilities.

Potential Benefits

There are many benefits to the hospital-at-home model (Table). This health care model can be particularly helpful for patients who require frequent admission to acute care facilities, and is well suited for patients with a range of conditions, including those with COVID-19, pneumonia, cellulitis, or congestive heart failure. This care model helps eliminate some of the stressors for patients who have chronic illnesses or other conditions that require frequent hospital admissions. Patients can independently recover at home and can also be surrounded by their loved ones and pets while recovering. This care approach additionally eliminates the risk of hospital-acquired infections and injuries. The hospital-at-home model allows for increased mobility,² as patients are familiar with their surroundings, resulting in reduced onset of delirium. Additionally, patients with improved mobility performance are less likely to experience negative health outcomes.³ There is less chance of sleep disruption as the patient is sleeping in their own bed—no unfamiliar roommate, no call bells or health care personnel frequently coming into the room. The in-home technology set up for remote patient monitoring is designed with the user in mind. Ease of use empowers the patient to collaborate with their care team on their own terms and center the priorities of themselves and their families.

Positive Outcomes

The hospital-at-home model is associated with positive outcomes. The authors of a systematic review identified 10 randomized controlled trials of hospital-at-home programs (with a total of 1372 patients), but were able to obtain data for only 5 of these trials (with a total of 844 patients).⁴ They found a 38% reduction in 6-month mortality for patients who received hospital care at home, as well as significantly higher patient satisfaction across a range of medical conditions, including patients with cellulitis and community-acquired pneumonia, as well as elderly patients with multiple medical conditions. The authors concluded that hospital care at home was less expensive than admission to an acute care hospital.⁴ Similarly, a meta-analysis done by Caplan et al⁵ that included 61 randomized controlled trials concluded that hospital at home is associated with reductions in mortality, readmission rates, and cost, and increases in patient and caregiver satisfaction. Levine et al² found reduced costs and utilization with home hospitalization compared to in-hospital care, as well as improved patient mobility status.

The home is the ideal place to empower patients and caregivers to engage in self-management.² Receiving hospital care at home eliminates the need for dealing with transportation arrangements, traffic, road tolls, and time/scheduling constraints, or finding care for a dependent family member, some of the many stressors that may be experienced by patients who require frequent trips to the hospital. For patients who may not be clinically suitable candidates for hospital at home, such as those requiring critical care intervention and support, the brick-and-mortar hospital is still the appropriate site of care. The hospital-at-home model helps prevent bed shortages in brick-and-mortar hospital settings by allowing hospital care at home for patients who meet preset criteria. These patients can be hospitalized in alternative locations such as their own homes or the residence of a friend. This helps increase health system capacity as well as resiliency.

In addition to expanding safe and appropriate treatment spaces, the hospital-at-home model helps increase access to care for patients during nonstandard hours, including weekends, holidays, or when the waiting time in the emergency room is painfully long. Furthermore, providing care in the home gives the clinical team valuable insight into the patient’s daily life and routine. Performing medication reconciliation with the medicine cabinet in sight and dietary education in a patient’s kitchen are powerful touch points.² For example, a patient with congestive heart failure who must undergo diuresis is much more likely to meet their care goals when their home diet is aligned with the treatment goal. By being able to see exactly what is in a patient’s pantry and fridge, the care team can create a much more tailored approach to sodium intake and fluid management. Providers can create and execute true patient-centric care as they gain direct insight into the patient’s lifestyle, which is clearly valuable when creating care plans for complex chronic health issues.

Although there are clear benefits to hospital at home, how to best implement and scale this model presents a challenge. In addition to educating patients and families about this model of care, health care systems must expand their hospital-at-home programs and provide education about this model to clinical staff and trainees, and insurers must create reimbursement paradigms. Patients meeting eligibility criteria to enroll in hospital at home is the easiest hurdle, as hospital-at-home programs function best when they enroll and service as many patients as possible, including underserved populations.

Upfront Costs and Cost Savings

While there are upfront costs to set up technology and coordinate services, hospital at home also provides significant total cost savings when compared to coordination associated with brick-and-mortar admission. Hospital care accounts for about one-third of total medical expenditures and is a leading cause of debt.² Eliminating fixed hospital costs such as facility, overhead, and equipment costs through adoption of the hospital-at-home model can lead to a reduction in expenditures.

Brick-and-mortar hospitals in the United States have historically been considered the dominant setting for providing care to patients. The coordination and delivery of care has previously been bound to physical hospitals largely because multidisciplinary services were only accessible in an individual location. While the fundamental make-up of these services remains unchanged, these services are now available in alternate settings. Some of these services include access to a patient care team, supplies, diagnostics, pharmacy, and advanced therapeutic interventions. Presently, the physical environment is becoming increasingly irrelevant as the core of what makes the traditional hospital—the professional staff, collaborative work processes, and the dynamics of the space—have all been translated into a modern digitally integrated environment. The elements necessary to providing safe, effective care in a physical hospital setting are now available in a patient’s home.

Impetus for the Model

As hospitals reconsider how and where they deliver patient care because of limited resources, the hospital-at-home model has gained significant momentum and interest. This model transforms a home into a hospital. The inpatient acute care episode is entirely substituted with an intensive at-home hospital admission enabled by technology, multidisciplinary teams, and ancillary services. Furthermore, patients requiring post-acute support can be transitioned to their next phase of care seamlessly. Given the nationwide nursing shortage, aging population, challenges uncovered by the COVID-19 pandemic, rising hospital costs, nurse/provider burnout related to challenging work environments, and capacity constraints, a shift toward the combination of virtual and in-home care is imperative. The hospital-at-home model has been associated with superior patient outcomes, including reduced risks of delirium, improved functional status, improved patient and family member satisfaction, reduced mortality, reduced readmissions, and significantly lower costs.¹ COVID-19 alone has unmasked major facility-based deficiencies and limitations of our health care system. While the pandemic is not the impetus for the hospital-at-home model, the extended stress of this event has created a unique opportunity to reimagine and transform our health care delivery system so that it is less fragmented and more flexible.

Nursing in the Model

Nursing is central to the hospital-at-home model. Virtual nurses provide meticulous care plan oversight, assessment, and documentation across in-home service providers, to ensure holistic, safe, transparent, and continuous progression toward care plan milestones. The virtual nurse monitors patients using in-home technology that is set up at the time of admission. Connecting with patients to verify social and medical needs, the virtual nurse advocates for their patients and uses these technologies to care and deploy on-demand hands-on services to the patient. Service providers such as paramedics, infusion nurses, or home health nurses may be deployed to provide services in the patient’s home. By bringing in supplies, therapeutics, and interdisciplinary team members, the capabilities of a brick-and-mortar hospital are replicated in the home. All actions that occur wherever the patient is receiving care are overseen by professional nursing staff; in short, virtual nurses are the equivalent of bedside nurses in the brick-and-mortar health care facilities.

Potential Benefits

There are many benefits to the hospital-at-home model (Table). This health care model can be particularly helpful for patients who require frequent admission to acute care facilities, and is well suited for patients with a range of conditions, including those with COVID-19, pneumonia, cellulitis, or congestive heart failure. This care model helps eliminate some of the stressors for patients who have chronic illnesses or other conditions that require frequent hospital admissions. Patients can independently recover at home and can also be surrounded by their loved ones and pets while recovering. This care approach additionally eliminates the risk of hospital-acquired infections and injuries. The hospital-at-home model allows for increased mobility,² as patients are familiar with their surroundings, resulting in reduced onset of delirium. Additionally, patients with improved mobility performance are less likely to experience negative health outcomes.³ There is less chance of sleep disruption as the patient is sleeping in their own bed—no unfamiliar roommate, no call bells or health care personnel frequently coming into the room. The in-home technology set up for remote patient monitoring is designed with the user in mind. Ease of use empowers the patient to collaborate with their care team on their own terms and center the priorities of themselves and their families.

Positive Outcomes

The hospital-at-home model is associated with positive outcomes. The authors of a systematic review identified 10 randomized controlled trials of hospital-at-home programs (with a total of 1372 patients), but were able to obtain data for only 5 of these trials (with a total of 844 patients).⁴ They found a 38% reduction in 6-month mortality for patients who received hospital care at home, as well as significantly higher patient satisfaction across a range of medical conditions, including patients with cellulitis and community-acquired pneumonia, as well as elderly patients with multiple medical conditions. The authors concluded that hospital care at home was less expensive than admission to an acute care hospital.⁴ Similarly, a meta-analysis done by Caplan et al⁵ that included 61 randomized controlled trials concluded that hospital at home is associated with reductions in mortality, readmission rates, and cost, and increases in patient and caregiver satisfaction. Levine et al² found reduced costs and utilization with home hospitalization compared to in-hospital care, as well as improved patient mobility status.

The home is the ideal place to empower patients and caregivers to engage in self-management.² Receiving hospital care at home eliminates the need for dealing with transportation arrangements, traffic, road tolls, and time/scheduling constraints, or finding care for a dependent family member, some of the many stressors that may be experienced by patients who require frequent trips to the hospital. For patients who may not be clinically suitable candidates for hospital at home, such as those requiring critical care intervention and support, the brick-and-mortar hospital is still the appropriate site of care. The hospital-at-home model helps prevent bed shortages in brick-and-mortar hospital settings by allowing hospital care at home for patients who meet preset criteria. These patients can be hospitalized in alternative locations such as their own homes or the residence of a friend. This helps increase health system capacity as well as resiliency.

In addition to expanding safe and appropriate treatment spaces, the hospital-at-home model helps increase access to care for patients during nonstandard hours, including weekends, holidays, or when the waiting time in the emergency room is painfully long. Furthermore, providing care in the home gives the clinical team valuable insight into the patient’s daily life and routine. Performing medication reconciliation with the medicine cabinet in sight and dietary education in a patient’s kitchen are powerful touch points.² For example, a patient with congestive heart failure who must undergo diuresis is much more likely to meet their care goals when their home diet is aligned with the treatment goal. By being able to see exactly what is in a patient’s pantry and fridge, the care team can create a much more tailored approach to sodium intake and fluid management. Providers can create and execute true patient-centric care as they gain direct insight into the patient’s lifestyle, which is clearly valuable when creating care plans for complex chronic health issues.

Although there are clear benefits to hospital at home, how to best implement and scale this model presents a challenge. In addition to educating patients and families about this model of care, health care systems must expand their hospital-at-home programs and provide education about this model to clinical staff and trainees, and insurers must create reimbursement paradigms. Patients meeting eligibility criteria to enroll in hospital at home is the easiest hurdle, as hospital-at-home programs function best when they enroll and service as many patients as possible, including underserved populations.

Upfront Costs and Cost Savings

While there are upfront costs to set up technology and coordinate services, hospital at home also provides significant total cost savings when compared to coordination associated with brick-and-mortar admission. Hospital care accounts for about one-third of total medical expenditures and is a leading cause of debt.² Eliminating fixed hospital costs such as facility, overhead, and equipment costs through adoption of the hospital-at-home model can lead to a reduction in expenditures. It has been found that fewer laboratory and diagnostic tests are ordered for hospital-at-home patients when compared to similar patients in brick-and-mortar hospital settings, with comparable or better clinical patient outcomes.⁶ Furthermore, it is estimated that there are cost savings of 19% to 30% when compared to traditional inpatient care.⁶ Without legislative action, upon the end of the current COVID-19 public health emergency, the Centers for Medicare & Medicaid Service’s Acute Hospital Care at Home waiver will terminate. This could slow down scaling of the model.However, over the past 2 years there has been enough buy-in from major health systems and patients to continue the momentum of the model’s growth. When setting up a hospital-at-home program, it would be wise to consider a few factors: where in the hospital or health system entity structure the hospital-at-home program will reside, which existing resources can be leveraged within the hospital or health system, and what are the state or federal regulatory requirements for such a program. This type of program continues to fill gaps within the US health care system, meeting the needs of widely overlooked populations and increasing access to essential ancillary services.
